If you do the quest for this after you already have a gem boutique (like I did, on a boosted toon who was given lvl 700 in proffs & a garrison w/ a gem boutique automatically in the boost), then it will fail and/or say "you already know this spell", so it'll have to be manually deleted. At least the lvl 1 building blueprint can be vendored.
